SQL Query

I have this requirement to write a SQL query:

Players get one entry for every 250 they deposit and then play. So if they deposit 250 one day and wager 500, they still only get 1 entry that day.
For each entry they must have deposited 250 and wagered 250. If they deposit 500 in one go and then wager 500 then its 2 entries.

So when updating daily, it must take into consideration the previous days activity (any previous promotion days) if they deposit 500 on day 1 and only wager 250, they would get 1 entry on day 1. But if then on day 2 the player wagers another 250, they would get another entry following on from previous activity. So entry count at the end of day 2 would be 2.


There is a table that captures deposits made by each player( AmountPTY), there is a playeraccount with account id for each player, there is a table that captures play for each player (BetAmtPTY).

I have done the query but its running for too long within my stored procedure.

Please feel free to correct what I have done. The important bit is the T-SQL that tracts deposit and play.

Thanks

[CASE
                  WHEN FLOOR(SUM(BetAmtPTY) /250 * 1) > 0 AND FLOOR(SUM(AmountPTY) / 250) * 1 > 0
                  AND FLOOR(SUM(BetAmtPTY) /250 * 1) = FLOOR(SUM(AmountPTY) / 250) * 1 THEN  (SUM(BetAmtPTY)/250) * 1
                  WHEN FLOOR(SUM(BetAmtPTY) /250 * 1) > 0 AND FLOOR(SUM(AmountPTY) / 250) * 1 > 0
                  AND FLOOR(SUM(BetAmtPTY) /250 * 1) < FLOOR(SUM(AmountPTY) / 250) * 1 THEN  (SUM(BetAmtPTY)/250) * 1
                  WHEN FLOOR(SUM(BetAmtPTY) /250 * 1) > 0 AND FLOOR(SUM(AmountPTY) / 250) * 1 > 0
                  AND FLOOR(SUM(BetAmtPTY) /250 * 1) > FLOOR(SUM(AmountPTY) / 250) * 1 THEN  (SUM(AmountPTY)/250) * 1
                  WHEN FLOOR(SUM(BetAmtPTY) /250 * 1) > 0 AND FLOOR(SUM(AmountPTY) / 250) * 1 < 0 THEN '0'
                  WHEN FLOOR(SUM(BetAmtPTY) /250 * 1) < 0 AND FLOOR(SUM(AmountPTY) / 250) * 1 > 0 THEN '0'
                  WHEN FLOOR(SUM(BetAmtPTY) /250 * 1) < 0 AND FLOOR(SUM(AmountPTY) / 250) * 1 < 0 THEN '0'
                  ELSE 0
                  END ]

Hi,

I would like to rewrite this as the following.
Also *1 does not achieve much and can be dropped.
You can try this as well as CTE, depending on what is the remaining portion of your query.
CASE
                 WHEN BAmt > 0 AND AAmt > 0 AND BAmt <= AAmt THEN  SBAmt
                 WHEN BAmt > 0 AND AAmt > 0 AND BAmt > AAmt  THEN  SAAmt
                 ELSE 0
END 

Where
FLOOR(SUM(BetAmtPTY) /250 * 1) 		BAmt
FLOOR(SUM(AmountPTY) / 250) * 1 	AAmt
(SUM(BetAmtPTY)/250) * 1 		SBAmt
(SUM(AmountPTY)/250) * 1		SAAmt

Open in new window

how can I configure this case statement or use any other construct to select only one and only one of the outcomes fro each player. the two columns I am comparing are BetAmountpty  (wagering) and AmountPTY (deposit)

Thanks

Do GROUP BY on player_id and use SUM before these CASE statement
